It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage, 1.65V to 5.5V, the PI5A4765 has a low On-Resistance of 0.6Ω @ 2.7V. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, INX, tolerates input drive signals up to 6.0V, independent of supply voltage. The PI5A4765 offers a headphone & mute detection function through utilization of an on-chip parator. When the negative terminal of the parator (P-) is less than the threshold (internally set to VCC/3, P0 (parator output) is a logic high. A logic low on P0 occurs when P- rises above the the threshold. PI5A4765 also offers shunt switches connected to ground in order to dissipate capacitance that builds up on the unconnected NC or NO line. As a result, reduction of popping and clicking sounds is achieved when switching between audio sources.
